PORTABLE CREMATING-CLOSET AND GARBAGE-DESTRUCTOR.

Specification of Letters Patent.

Patented Jan. 28, 1913.

To all whom it may concern Be it known that I, NATHANIEL Fnos'r, a citizen of the United States, and a resident of Bloomington, in the county of McLean and State of Illinois, have invented a new and Improved Portable Cremating-Closet and Garbage-Destructor, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved portable cremating closet and garbage destructor, more especially designed for use in camps and other places having no sewers, and arranged to incinerate excreta and to evaporate urine, etc., to destroy garbage or other loose material and. to utilize the loose material as fuel for incinerating purposes.

In order to accomplish the desired result,

. use is made of a sectional flue connected at one end with a furnace and at the other end with a chimney, each flue section having an opening at the top, an evaporating pan at the bottom and a drying plate within the section above the corresponding evaporating pan, a closet casing or hopper held on top of each flue section, and a reversible receiving plate within the said hopper receiving the excrement and dumping the same through the flue top opening onto the drying plate.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a rear side elevation partly in section of the portable cremating closet and garbage destructor; Fig. 2 is a plan View of the same; Fig. 3 is an enlarged sectional side elevation of one of the closets and the garbage destructor; Fig. 4: is a transverse section of the same on the line 4-4= of Fig. 3; and Fig. 5 is an enlarged cross section of one of the portable cremating closets.

A flue A is made in sections bolted or otherwise removably fastened together so as to permit of conveniently assembling the flue sections or to take the same apart for convenient transportation from one place to another. Sundry of the flue sections are provided with suitable legs B to support the flue a distance above the ground or other place on which the apparatus is located. One end of the flue A is connected with a furnace C, and the last end section of the flue is provided at the top with a chimney D. Each of the flue sections A is provided at the top with an opening A and on each flue section, except the last one carrying the chimney D, is bolted or otherwise removably secured a removable closet casing or a hopper E provided on top with a closet seat F having a. cover G. A platform H is arranged on the front of the fine to permit of conveniently reaching the several closets.

IVithin each hopper E is arranged a recciv ing plate I provided at the sides with trunnions I journaled in the sides of the hopper E to permit of turning the receiving plate I with a view to bring either face upward and to dump the excrement into the flue A. The receiving plate I is normally in a horizontal position and is in close proximity to the corresponding opening A so as to practically close the same. One of the trunnions I is provided at the outer end with an angular arm I connected with a rod J extending upwardly and guided in a suitable bearing J attached to the upper end of the hopper E so that the rod J is within convenient reach of the user of the closet to allow of conveniently reversing the plate I for dumping the excrement thereon into the flue A. The upper end of each hopper E is provided with openings E for circulating air through the upper portion of the hopper E to prevent the same from becoming unduly heated by the heat passing through the flue A.

In the lower portion of each flue section A is arranged a perforate receiving plate K disposed horizontally and mounted on suitable brackets K attached to the flue section, and the bottom of each flue section A immediately below the receiving plate K is provided with an evaporating pan L, the several evaporating pans decreasing in shallowness from the outer section of the flue A toward the garbage destructor C. The bottomof the flue A is slightly inclined upwardly from the furnace C to the outer end so that the liquid accumulating in the pans L can overflow from one pan into the next deeper one, and as the deepest pan is nearest the most intense heat, it is evident that a proper evaporation of the liquid takes place.

It will be seen that when a closet is used the excrement dropped onto a receiving plate I is dumped by the latter on turning it as previously explained, so that the excrement drops onto the receiving plate K to be incinerated thereon by the heat passing through the flue A from the garbage destructor C. By supporting the receiving plate K a distance above the bottom of the flue A the heat can readily pass over and under the plate, thus insuring a proper incineration in a comparatively short time.

A urinal of any approved construction is attached to the back of each flue section A to discharge into the latter a distance above the receiving plate K so that the urine passes onto the said plate K to be evaporated by the heat passing through the flue A. The urine or other liquid or semiliquid matter, not immediately evaporated passes into the corresponding evaporating pan L to be evaporated by the heat passing through the flue A and over the open top of the pan.

The furnace C, shown in detail in Figs. 3 and 4c, is made in sections adapted to be bolted or otherwise fastened together, and the furnace is provided with a combustion chamber 0 and a grate P, below which is arranged an ash pit Q. Fuel can be passed into the combustion chamber 0 and onto the grated through a door 0 at the right-hand end of the furnace, the said end being also provided with an ash pit door Q for receiving the ashes from the ash pit Q. The left hand portion of the furnace C is provided with a drying chamber R, the lower portion of which connects with the beginning end of the flue A, and the upper portion of the drying chamber R is provided with a perforate plate S inclined downwardly toward the outer end of the furnace, the plate being supported on suitable brackets S attached to the inside of the furnace. Directly above the plate S is arranged a charging door T on the top of the furnace for dumping garbage or other loose material onto the plate S so that the garbage is subjected to the heat from the burning fuel on the grate P with a view to dry the said material. Then this has been done, the operator in charge of the apparatus rakes the dried materal off the plate S into the combustion chamber 0 and onto the fuel, so as to utilize the dried material as fuel. A door 0 arranged on the outer end of the furnace C permits convenient introduction of raking tools for the combustion chamber 0. A perforate moisture that may drop from the garbage or other material placed onto the perforate plate S.

When the apparatus is in use, the heatfrom the burning fuel in the furnace C passes through the flue A to the chimney D, and in doing so the several receiving plates I are heated to insure proper sterilization of the plates. The excrements are dumped, on reversing the plate 1, into the flue A, the excrements falling onto the receiving plate K to be subjected to the heat passing through the flue so as to incinerate the same. The urine or other moisture in' the pans L is quickly evaporated by the heat passing through the flue and over the open ends of the said pans. Garbage and other loose material are introduced into the furnace O through the door P, dried on the plate S and then used as fuel in the furnace, thus rendering the apparatus exceedingly economical in its use.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. A portable cremating closet, comprising a sectional flue, each flue section having an opening at the top, a furnace connected with one end of the flue, a chimney connected with the other end of the flue, a drying plate within each flue section below the top opening, a closet hopper on top of each flue section and provided with a closet seat, and a reversible receiving plate in the said hopper for receiving excrement and dumping it onto the said drying plate.
